What is a radio?

i have a new member asking me whats everyone talking about radio. its hard for me to explain. so i created a post so everyone who can explain it let the hole bbos crew no ok. i had a thread on it but cant find it. please explain the radio.

I asked this same question. The answer I got (if I remember and understand correctly) is that the radio file is the the "core" of the OS. I used to read radio file and think transmitter/receiver but actually it is the basis and BASE of the OS.

Here is an explanation I found awhile ago provided by TBacker that really explains it well

The sfi file (some call it the radio file but it's much more) contains essentially the core of the OS. It's the Blackberry kernel and the Java virtual machine (VM) that actually runs the programs. Think of it as similar to the Windows kernel. There's a version for each type of hardware, just like there's a Windows x86, 64 bit, embedded, etc. It interfaces directly with the hardware, runs the applications, and provides the means for applications to interact with the hardware of the device.The sfi can directly affect hardware performance (graphics, touch, click, radios, power use, etc) because it directly controls it. It can also benefit or detract from any apps running on top of it.

The radio is the .sfi file. It basically lets the phone fine service...think of it more as the base to the os, with out it your phone will not work. It can affect battery life, signal strength, speed of your phone, It is basically the brain of the phone
